STREET-=RECElVER AND STENCH-TRAP.

SPECIFICATION iorming part of Letters Patent No. 357,733, dated February 15, 1887.

Application filed November (1', 1886. Serial No. 218,151. (No model.)

To aZZ whom it may concern:

Be it known that I, THOMAS J. OBRIEN, a

citizen of the United States, residing in Buffalo, in the county of Erie and, State of New York, have invented certain new and useful Improvements in Street-Recei vers and Stench- Traps, of which the following is a specification.

. My invention relates to an additional improvement on the street-receiver and stenchtrap for which I received a patent, No.343, 335, dated June 8, 1886; and it consists in the combination therewith of an antoinaticallyacting valve, which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which certain portions of the old invention are shown, so as to more clearly show and describe what is new.

Figure 1 represents a side elevation of the receiver complete. Fig. 2 is also a side elevation of the same, showing one side taken off, and a vertical central section through the bottom, so as to expose the interior construction and show the automatically-acting valve in position. Fig. 3 is a plan or top view showing a horizontal section through line A A, Fig, 2. Fig. 4 is a detached top view of the valve on a reduced scale; and Fig. 5 represents a port-ion of one side of the receiver, showing the ribs and seat thereon for supporting the valve, the valve being left oii' so as to show them more clearly.

The body of the receiver consists of two side pieces, 1 and 2, and a hollow bottom piece, 3, having a cross-piece, 4, projecting down into the concave portion of the bottom and forming a trap to catch the dirt, &c. These parts are secured together by the flanges 5, 6, 7, 8, 9, and 10 and the bolts 11.

12 is the outlet-opening, and 13 represents slideways to receive the plate orshut-off 14; but as these parts are fully described and shown in my said Letters Patent No. 343,335, a further description here is unnecessary.

Each of the side pieces, 1 and 2, is provided with ribs 15 and 16, set 011 a downward incline, as shown, and between these two ribs, on each side of the receiver, is a seat, 17, to receive the pivotal shoulders of the valve.

It will be noticed that the upper portion, 18, of the valve is wider than the lower p0rtion, 19, so as to leave the shoulders 20, which act as pivots to the valve and upon which it swings in the seats 17 at each side of the receiver. The narrow portion 19 adapts the" valve to be entered or placed in position in the seat 17 between the ribs 15, upon which its widest portion rests when shut.

The ribs 16 are made wide enough to cover a small portion of the sides of the lower portion of the valve, so that it can rest up against it when closed, as shown in Fig. 3, where the narrow portion 19 of the valve is shown by dotted lines, and the lower ribs, 15, below the valve are shown by the dotted lines 21.

A pin or stop, 22, is placed on one or both sides of the receiver, to prevent the valve from swinging open too far. (See Fig. 2, also Fig. 5, where the valve is shown by the dotted lines 23 inits position when open.)

The object of this valve is to keep the receiver closed except when water or other matter is passing in through it, after which it iminediately closes automatically by the additional weight of its upper portion, 18. It also serves to detain sticks, straw, or other material that ruight get into and obstruct the lower portion of the receiver, and is a further means (in addition to the trap) for preventing the escape of sewcr-gas,should any escapethrough the trap, as the water and mud which settle in the seams between the valve and the sides of the receiver soon seal it, so as to be gastight from any pressure below until opened by a preponderance of weight on the top of the downwardly-inclincd lower side, 19, caused by water or other material while passing in, alter which it again closes and becomes scaled, as above mentioned.

It will be noticed that as the valve inclinesdownward the water in passing in will go to the lower portion of the valve, when its weight is in the proper position to open the valve. The valve is provided with a handle, 25.

I claim as my invention- In astreet-receiver and stench-trap, the combination therewith of the downwardly-inclined ribs 15 and 16 and an automaticallyacting valve, consisting of the upper andlower portions, 18 and 19, and pivotally seated in bearings 17, whereby the valve is adapted to be opened by water or other matter passing into the receiver, and to close automatically when relieved of the weight of such material, substantially as described.
